Had a quick look over Marshall - not sure at first glance whether much needs added or changed. Seems very nicely covered.

May I suggest you take a peek at something else tho - which may be of interest. Guy on THR not so long ago put together a chart type deal with a lot of small guns and it does give some quite handy representative comparisons. It went thru several incarnations but IIRC the one I show is pretty much his latest.

It is on my R9 FAQ site and this is the relevent page. You'll see a link to a PDF file - the pic on that page is only for starters, as definition not brilliant.

What about the ORIGINAL pocket gun... the Derringer. I don't see it mentioned anymore. Where can you get a major defense caliber, like .38, 9mm or .45 in a gun the size of a Kel Tec. While it may have fewer shots compared to the semi-autos or revolvers, it's much more concealable than 99% of them and I would not feel unarmed with two shot's of 9mm or even .45 in my pocket. Also, they can be purchased for as little as $100 in most cases. I've had a Davis .32 for over 15 years and NEVER had a malfunction. The gun is simplicity itself and takes 2 seconds to break down for cleaning or relaoding. I almost bought another last month in 9mm, but was talked into buying a KT P3AT instead. I like the KT, but it cost twice as much as the Derringer and a derringer never has a FTF/FTE problem or lost mags. Something to consider!

If the definition is a pistol that will fit in the pocket, how about the Bersa Thunder 380? I've got one, and it fits in all my pants pockets with no problem. It's not wide, has fairly flat sides, and in most of my pants makes no imprint.

Shucks - I had not given consideration to Derringers so yeah - they certainly could feature and then as Al mentions - the Thunder .380. I have one (well - wife has ''taken it over''!) - but in the right pocket that can disappear.

Perhaps the rear pocket test is a little harsh, as so much depends on pants style - plus, my wife can carry the Bersa very nicely this time of year in the big front pocket of a ''hoodie'' sweatshirt/fleece type deal.

"There are also those who claim that Smith and Wesson Ultralight J-frame revolvers can be pocket guns. Some of them are definitely light enough. For example the 342 Airlite Titanium weighs only 12 ounces, and carries five .38 special cartridges. However the j-frame revolvers are really too long (6.5 inches) and thick (1.3 inches) to be true pocket pistols."

J frames NOT fit for pocket holsters???!! I think you need to research that a bit more, sir. I am not trying to falem you or be disrespectful.
At least one state issues J frames for off side front pocket carry for their troopers.
Guys from the size of 5'9" Massad Ayoob to 6'7" Bill Jordan carry (past tense for Mr.Jordan) J frames in the left hand front pocket.
I have carried a 442 for 12 years, a M60 or a 642 for 4 years and a CA Off Duty before that for 5 years. I carried a 3" 632 when wearing Dockers for a few years it worked great.
J frame sized guns are pocket guns with the right attire and holsters. I have carried mine in everything from jeans to dress slacks in jobs from construction to banking.
J frames are the standard by which I measure all other pocket pistols.

One of my reasons for choosing a pocket gun would not be one that you can shoot in your pants pocket.I can't even imagine having to do that. In a loose fitting coat,jacket,or vest,with large pockets, is something else. Take a look at the specs of the little KelTec .32's and especially the .380's. Remembering that thickness of weapon really counts for a pocket piece.For the overall size(dementions) weight,and firepower, is their anything smaller ?? --------
